A car crash on Farrington Highway near St. John's Road in Maili on Friday morning brought a utility pole down, causing non-electrical lines to be pulled onto the roadway, Honolulu police said.
The male driver was taken to the hospital in serious condition after the incident happened just after 3:15 a.m., according to authorities on scene.
A city bus headed westbound was hit by the falling lines shattering the upper right side of the front window.
No other injuries were reported.
Hawaiian Telcom and Oceanic Time Warner Cable will be making repairs.
Up to 300 phone users, 200 Internet users and 100 television users may be impacted, Hawaiian Telcom officials said.
Crews with Oceanic said their services were not impacted.
Police earlier closed Farrington Highway between St. John's Road and Maliona Street, but it has since been reopened.
Drivers should expect possible lane closures during day as needed, while Hawaiian Telcom crews replace the telephone pole and repair the lines.
